Thanks Maxime for the advice and for Ludo' for applying the change!

I've rebased the patches from Stefan and there are only two packages that don't cross-compile - nss-certs and ntp.

I attempted to do guix pull on Raspberry Pi 3, but it failed due to running of memory - I'll attempt to test it with a swap file/partition.

Or is it possible to do guix pull using a substitute so that the computation wouldn't be done locally? This offloading would be really great for these embedded platforms.
